So I was following a truck today with 2 snowmobiles (or snow machines if you are in Alaska) and I thought what a great reverse trike they would make. The nose has better aero then some motorcycles, they seem to sit a bit lower, and a full aero body would be easier to build on one then a motorcycle. The skid mounts where the front wheels sit seem far enough forward and outboard to allow for a nice wheel faring. Then I googled it and saw that it's already a thing.
